Abstract:

Features of residual oil in gas condensate reservoirs. The mechanisms of formation of residual oil in oil-saturated reservoirs are well known [1], they can qualitatively differ from the mechanisms determining the presence of residual oil in gas-saturated and gas-condensate-saturated reservoirs. Accordingly, it is of interest to study the properties of residual oil in gas condensate reservoirs. The ability to study the composition and properties of residual hydrocarbons is provided by their extraction from the core material with subsequent analysis of the extracts obtained. The existence of a submarine cryolithozone is determined mainly by two reasons: the negative temperature of the bottom layers of water (modern conditions) and deep freezing during the geological period (paleoconditions). According to its physical state, the cryolithozone can be frozen (ice-containing) and unfrozen, represented by cooled mineralized waters and rocks.

Keywords: IR spectroscopy, characteristics, gas condensate field, gas composition, submarine cryolithozone
